Pros
On principal, the company is supportive of telework. With the broad scope of business, there are opportunities for literally thousands of different skill sets. The company provides a lot of different opportunities for professional development provided the budget and scope is supported by your lowest level manager. I have been very satisfied with the salary level.
Cons
Technologically, the support for teleworkers is lacking considerably. The company is huge and as a result is riddled with corporate bureaucracy. The government contracting field is not for everyone (myself included). As the company grows and changes strategies, the individual begins to seem ever-increasingly expendable. I do not feel secure any longer than my project's contract end date.
